CROSS-REFERENCE To RELATED APPLICATIONS

This application is a continuation in part of pending U.S. Non-Provisional patent application Ser. No. 14/838,357, filed Aug. 27, 2015, that claims the benefit of U.S. Provisional Patent Application No. 62/044,068, filed Aug. 29, 2014.

TECHNICAL FIELD

This invention relates to firearm safety devices. More particularly, the present invention relates to firearm trigger blocks.

BACKGROUND

There is a long recognized need for preventing accidental discharge of firearms. In the United States alone, it is estimated that there are around 50 million households with at least one firearm. There are estimated to be about 190 million to 300 million privately owned firearms. A best estimate is that there are 22 million children living in homes with guns. The homeowner insists on the firearm being available for defense of family and property and thus keeps the firearm loaded. The typical homeowner then hides the weapon from the children, such as placing it on a high shelf or bedside in a drawer or under a pillow. However, the homeowner typically underestimates the knowledge and action of children. While the homeowner believes that the firearm is safely hidden, surveys of school-age children indicate that a high percentage know the location of the family firearm and a major portion of those have actually accessed the firearm and handled it. No wonder that there are approximately two fatal shootings daily involving young children! Emergency rooms report a dismaying percentage of their traffic is firearm wounds.

There have been many attempts at firearm locking devices, but gun shops report few sales of these devices, in spite of firearm owner interest in other accessories. Most have been rejected by firearm owners as too bulky and inconvenient, which can interfere with operation of the firearm and ability to use the firearm in the anticipated emergency. A popular lock requires a key that may be unavailable, forgotten, or not readily accessible during emergency situations.

SUMMARY

In a first embodiment there is provided a trigger block and tamper notification system for use on a firearm. This trigger block has the following: a. a main enclosure assembly having a housing and at least two protruding elements designed to position, respectively, in front of and in back of a firearm trigger, the protruding element in back of the firearm trigger having a circular base; b. a slide assembly including a slide housing and two channels to receive the two protruding elements; c. the protruding element in front of the trigger having a magnetic reed switch; d. the channel receiving the protruding element with the magnetic reed switch being adjacent to a magnet switch mounted in the slide assembly; e. a keypad on the main enclosure assembly, the keypad connecting to a control module and having at least four keys, the four keys enabling input of a secret four-digit number to arm or disarm at least one signaling element; and f. the control module being in communication with at least one signaling element, the signaling element(s) activated when the switch magnet is from away from the position adjacent to the reed switch.

In another embodiment, the trigger block and tamper notification system has a main enclosure assembly further including at least one indicator light to confirm keypad input.

In yet another embodiment, the trigger block and tamper notification system includes the protruding element behind the firearm trigger that also has a central post and at least one flange, such that when the circular base is turned, the protruding element fills the space behind the firearm trigger and prevents the firearm from being discharged.

In another embodiment, the trigger block and tamper notification system features the protruding element in front of the trigger that includes an inner end, a proximal end, a distal end and a row on either protruding side of parallel teeth.

In yet another embodiment, the trigger block and tamper notification system includes the slide assembly further includes a channel formed in the slide housing for the protruding element in front of the trigger, on opposing sides of which are a pair of, each pawl including a latch end and a release end and a mounting on a pivot pin intermediate the latch end and the release end, the pivot providing for movement between an engage position of engaging the parallel teeth of the protruding element, in which the latch end extends into the channel and a release position in which the latch end is withdrawn from the channel; and biasing elements carried by the housing, the biasing maintaining the pawl elements in the engaged position.

DETAILED DESCRIPTION

We have become increasingly concerned with the prevalence of gun accidents particularly involving children. We have studied the current array of gun locks and particularly trigger blocks. We have noted that they are awkward and inconvenient. For the typical homeowner seeking family protection and acquiring a firearm for protection, the firearm must be readily available and any lock easily removed in an emergency. We analyzed the current trigger blocks and found that all significantly delay the response time, particularly when the owner is not familiar with them. With a trigger block, a child finding the firearm will not be harmed; however, the owner has no idea it has been tampered with and possible moved. Firearm thefts are also prevalent, and are not deterred by trigger blocks. Once stolen, the lock can be removed at leisure. In these instances, nothing indicates movement of the firearm from its proper location, and one cannot determine who tampered with or removed the firearm.

We established a new set of criteria for a new inventive trigger block, taking into account the circumstances surrounding child safety and gun owner priorities. First, the trigger block must be light weight and not interfere with handling of the firearm. Second, the trigger block must be easy to remove in an emergency. Third, the trigger block must be very difficult for a child, even a pre-teen, to remove without instruction. Fourth, the trigger block must incorporate a warning device, such as an alarm with a motion sensor, both to scare the child who moves the firearm and alert the parent to a teachable moment—or deter a stealthy burglar from taking the noisy article. Other criteria are highly beneficial and include tracking of the firearm to retrieve from a criminal, and coordination of our gun safety feature with the homeowner's security system and/or smart phone.

Turning now to the drawings in which like reference characters indicate corresponding elements throughout the several views, attention is directed to FIG. 1 which illustrates a firearm 20 and the trigger block generally designated with a 10. Trigger block 10 includes a main enclosure assembly 12 and a slide assembly 14. Main enclosure assembly 12 includes a housing 15 carrying an engagement member, which in this embodiment is a tapered probe element 16, and an adjustable blocking cam 17, each extending therefrom. Slide assembly 14 includes a slide housing 18 defining channels acting as complemental elements for receiving tapered probe element 16 and adjustable blocking cam 17, which will be described presently.

With additional reference to FIGS. 2, 3 and 7, trigger block 10 is illustrated in an installed position (FIGS. 2 and 3) and is fitted on a firearm 20 to prevent unauthorized use thereof. Main enclosure assembly 12 is positioned on one side of firearm 20 at trigger guard 22, with tapered probe element 16 passing through trigger guard 22 from one side, forward of a trigger 23 (FIG. 7) and adjustable blocking cam 17 extending through trigger guard 22 from the same side as tapered probe element 16, rearward of trigger 23 (FIG. 7). Slide assembly 14 is positioned on the opposing side of the firearm 20 and receives tapered probe element 16 and blocking cam 17. In this manner, firearm 20 is rendered inoperative until trigger block 10 is removed by an authorized user. As will be described presently, trigger block 10 also includes a tamper notification system which is activated if and when the firearm 20 is moved and/or the trigger block 10 is removed.

Referring now to FIG. 4, trigger block 10 is illustrated in a sectional view taken along lines 4-4 of FIG. 1. With additional reference to FIG. 5, main enclosure assembly 12 includes housing 15 having an inner end 25, an outer end 62, and defining an interior volume 28. Tapered probe element 16 extends outwardly from inner end 25, in an inwardly directed orientation with respect to trigger block 10. For purposes of orientation, the terms “inner”, “inward” and “inwardly directed” are intended to refer to a position or direction toward the firearm trigger guard 22 with trigger block 10 in the installed position. The terms “outer”, “outward” and “outwardly directed” are intended to refer to a position or direction away from the firearm trigger guard 22 with trigger block 10 in the installed position. Tapered probe element 16 is tapered from a proximal end 30 proximate inner end 25, to a distal end 32, and flattened on opposing side to accommodate the formation of a plurality of parallel teeth 33 angled outwardly with respect to trigger block 10, toward housing 15. Parallel teeth 33 are formed on the opposed flattened outer surfaces of tapered probe element 16, extending transverse to the longitudinal axis of tapered probe element 16. In this preferred embodiment, tapered probe element 16 defines an interior volume 35 in physical communication with interior volume 28 of housing 15 for purposes which will be described presently.

Inner end 25 of housing 15 further defines a socket 37 formed therein and positioned adjacent to tapered probe element 16. Socket 37 has a central aperture 38 formed therein, in physical communication with interior volume 28 of housing 15. Adjustable blocking cam 17 includes a central post 40 extending from a base 42 to a distal end 43. Base 42 is generally cylindrical in shape, and is rotatably received in socket 37, with central post 40 extending outwardly from inner end 25, in an inwardly directed orientation with respect to trigger block 10, and parallel to tapered probe element 16. Each of a pair of flanges 44 extend longitudinally along central post 40, from base 42 to a position spaced apart from distal end 43, and outwardly from opposing sides of central post 40. Circular base 42 snugly fits into socket 37 and can be adjusted for rotational movement and static positioning of circular base 42. In this embodiment, the fastening member is a screw 45 extending from interior volume 28, through central aperture 38 into base 42. By tightening screw 45, base 42, and therefore adjustable blocking cam 17, is held in a static position. When screw 45 is loosened, base 42, and therefore adjustable blocking cam 17, is free to rotate for purposes which will be described presently. Since adjustable blocking cam 17 extends through trigger guard 22 rearward of trigger 23 in the installed position, accommodation has been made to permit removal of adjustable blocking cam 17 in those instances where there is no space behind the trigger 23. In those instances, screw 45 is completely removed, and base 42 is removed from socket 37.

When adjustable blocking cam 17 is removed, it is possible to use the entire trigger block 10 to depress the trigger 23 and discharge the firearm 20. To prevent this occurrence, trigger block 10 can be turned 180 degrees so that while the engagement element still extends through the trigger guard 22 in front of the trigger 23, adjustable blocking cam 17 is positioned in front of the trigger guard 22. When properly adjusted, the interaction of adjustable blocking cam 17 with the front of the trigger guard 22 and the engagement element through the trigger guard 22 prevent movement of trigger block 10 and prevent discharge of the firearm 20.

Still referring to FIGS. 4 and 5, main enclosure assembly 12 further includes a control module 50 carried by housing 15 within interior volume 28. In the preferred embodiment, control module 50 is a printed circuit board supporting the various components used in the tamper notification system of the present invention. A magnetic reed switch 52 is carried within interior volume 35 of tapered probe element 16, and is electrically coupled to control module 50. Magnetic reed switch 52 is movable between an open and a closed configuration by an adjacent switch magnet 75 as will be disclosed presently. A magnetic reed switch 52 can be normally open and moved to the closed position by a magnet, or normally closed, and moved to the open position by an adjacent magnetic field. Control module 50 further includes a signaling element 53, which in this instance is a device for emitting an audio signal. One skilled in the art will understand that visual signals, such as flashing lights can also be employed or wireless signal to a remote device such as a cell phone and the like. A camera 55, a power source 56, such as a battery, and wireless transmitting elements are also carried by control module 50, and will be described in more detail presently. A cover 58 closes outer end 62 of housing 15, and includes central apertures 38 for egress of audio or visual signals, and a central aperture 38 to accommodate camera 55.

Still referring to FIG. 4, with additional reference to FIGS. 6, and 8, slide assembly 14 includes slide housing 18 having an inner end 60, an outer end 62, and defining a central channel 63 extending through slide housing 18 from inner end 60 to outer end 62. Central channel 63 and a pair of pawl elements 65 form the complemental element in the present invention. The pair of pawl elements 65 is mounted in slide housing 18, each element of the pair being mounted on opposing sides of central channel 63 and each includes a latch end 67 and a release end 68. Pawl elements 65 are each mounted on a pivot pin 70 and include intermediate latch end 67 and release end 68 for pivotal movement between an engage position and a release position. Biasing elements 72 bias pawl elements 65 into the engage position, in which latch end 67 extends radially into central channel 63. Biasing elements 72 are elastomeric compression pads mounted between an inset portion of slide housing 18 and release end 68. Pawl elements 65 are moved to the release position by compressing release ends 68 inwardly in the direction of arrowed lines D (FIG. 8), toward central channel 63 and against the bias of biasing elements 72. This movement results in latch ends 67 pivoting radially outwardly in the direction of arrowed lines E (FIG. 8), out of central channel 63. It will be understood that other biasing elements, such as compression springs, tension springs, torsion springs and the like, can be employed. A switch magnet 75 is mounted in slide housing 18 adjacent central channel 63 so as to be positioned adjacent magnetic reed switch 52 when slide assembly 14 is engaged with main enclosure assembly 12. Slide housing 18 additionally includes a receiving socket 73 for receiving the distal end 43 of adjustable blocking cam 17.

Still referring to FIG. 4, with additional reference to FIGS. 8 and 9, main enclosure assembly 12 and slide assembly 14 are coupled together by inserting tapered probe element 16 into central channel 63 from inner end 60 and distal end 43 of adjustable blocking cam 17 into receiving socket 73 as indicated by arrowed line C (FIG. 9). Main enclosure assembly 12 is fixedly coupled to slide assembly 14 by latch ends 67 of pawl elements 65 engaging parallel teeth 33, preventing withdrawal thereof. Tapered probe element 16 can be forcibly inserted into central channel 63, overcoming the bias of biasing elements 72. The angle of parallel teeth 33 and the bias prevents withdrawal of tapered probe element 16 therefrom. Removal of tapered probe element 16 is accomplished by depressing release ends 68, thereby moving pawl elements 65 from the engage position to the release position. This movement removes latch ends 67 from engagement with the parallel teeth 33. This can be accomplished by compressing opposing release ends 68 by the thumb and forefinger of one hand. The space between can be sufficient to prevent children from easily releasing the device. Additionally, the bias can be sufficient to prevent young children from being able to move the pawl elements 65 to the release position.

Turning now to FIGS. 7, 10 and 11, trigger block 10 is intended to be installed on a firearm 20, preventing unauthorized use thereof. Tapered probe element 16 passes through trigger guard 22 forward of trigger 23. The taper of tapered probe element 16 accommodates different sizes of trigger guards. Tapered probe element 16 is inserted until it tightly engages the trigger guard 22 in the vertical direction. This securely holds trigger block 10 in position on the firearm 20. Adjustable blocking cam 17 passes through trigger guard 22 rearward of trigger 23. Adjustable blocking cam 17 is then adjusted by rotation until one of flanges 44 engages the back of trigger 23 and the other engages trigger guard 22. Once this adjustment has been made, the tightening screw 45 is tightened, blocking cam 17 in position, requiring no further adjustment during future installation of trigger block 10 on that specific firearm 20. The position of flanges 44 prevents rearward movement of trigger 23. In this manner, trigger 23 is blocked in position, unable to move forwardly or rearwardly.

Turning now to FIG. 12, illustrated is the organization of tamper notification system that operates on the control module 50. As described briefly earlier, elements of control module 50 include a camera 55, which is preferably a single chip CCD camera, a power source battery 56 to power the various elements, and a magnetic reed switch 52 and switch magnet 75. If main enclosure assembly 12 is removed from slide assembly 14, tapered probe element 16 is removed from central channel 63 and magnetic reed switch 52 is no longer influenced by switch magnet 75 and changes between the open and closed positions. The switching of magnetic reed switch 52 provides a signal to control unit 85 in control module 50. This signal can result in various responses, such as a signal that the block has been removed generated by motion sensor 71 in control module 50. The signal can be audio, visual, or a signal from a wireless device 82 such as a ZigBee wireless transceiver chip, blue tooth and the like. The system further includes an omni directional motion sensor 71 which will initiate a signal if the firearm 20 is moved. Again, the signal can be audio, visual, and/or a wireless signal to a device such as a cell phone or other wireless device. These devices and signals are controlled by a control unit 85.

In use, the trigger block 10 can be set to provide a signal when it is moved and/or the block is released. This can be accomplished by an application, such as on an alarm (not shown) or a smart phone in communication with tamper notification system through transceiver chip 82. Control unit 85 can be programmed to set the motion sensor 71 and send a signal to the smart phone if the firearm 20 is moved. The control unit 85 can also be set to send a signal, such as to a cell phone if trigger block 10 is removed. Timers (not shown) can also be provided to prevent false alarms, such as a temporary tremor causing the motion sensor 71 to signal such a timer. If the motion does not repeat within a certain time or if the motion does not continue for a predetermined length of time, a signal is not sent. There are a large variety of combinations that can be achieved by the use of a motion sensor 71 to detect movement of the firearm 20, and a magnetic reed switch 52 to detect removal of trigger block 10, each of which can be programmed into control unit 85 through wireless communication devices or onboard control panel.

A basic set up procedure can be modified, and users should refer to the Operation Quick Guide provided with the particular trigger block 10. The trigger block 22 is preferably provided assembled but not armed. First, the owner disassembles the trigger block 22. The owner grasps the slide member with the cushion grip, depressing two opposing hidden buttons. This loosens the unit and allows separation of the main electronic probe assembly from the slide member.

Next, the owner needs to prepare the electronic probe assembly for use with the selected firearm 20 (side arm, rifle, shotgun, automatic, etc.). First, the electronics cover 58 near the keypad 87 needs to be removed by unscrewing the two tightening screws 45 with the use of the specially sized and included screwdriver. The electronics cover 58 has batteries and wires and must be gently removed only a short distance from the electronic probe assembly without pulling or stretching the wires. Initially the batteries may be equipped with insulator strips (not shown) which are removed by gently pulling the strips out one by one. Upon removal of the insulation strips the blue light indicator should be lit for a few seconds, indicating that the power system is working and ready for programming. The trigger block 22 is in neutral mode (programming is discussed below).

Next the owner inserts the main electronic probe assembly through the trigger guard 22 of the firearm 20, sliding the tapered probe in front of the trigger and the blocking cam 17 at the rear of the trigger 23. The electronic probe assembly is advanced until it touches the trigger guard 22 or the body of the firearm 20. Optionally the owner can rotate the blocking cam 17 to fill the space between the rear of the trigger 23 and the trigger guard 22 until the cam is wedged tightly between the trigger 23 and trigger guard 22. Optionally and if necessary, the electronic assembly slide can be adjusted to fit your firearm 20. With the electronic cover 58 still off, the owner can adjust the blocking cam 17 by first slightly loosening the tightening screw 45 at the base 42 of the blocking cam 17, just enough so you can rotate the blocking cam 17. Again the owner advances the electronic probe assembly until it touches the trigger guard 22 or body of the firearm 20 and rotates the blocking cam 17 to wedge the trigger 23 in place and render the trigger 23 inoperative. Then the owner tightens the blocking cam 17 screw. This is designed to prevent trigger 23 movement by manipulating the tapered probe rearward, thereby preventing misuse of the trigger block 22.

The electronic cover 58 is reassembled by inserting the electronic and battery boards back into the main electronic probe assembly and using the custom screw removal tool to reuse the two tightening screws 45 to reattach the electronic cover 58. Once that is accomplished, the trigger block 22 can be assembled on the firearm 20.

To install the trigger block 22 on firearm 20, the owner grasps the slide member between thumb and index finger on the elastomer cover 80 being careful to press in on both sides of the elastomer cover 80 to engage the slide assembly 14 firmly onto the main electronic probe assembly 12. Finger strength and dexterity are required, which makes it difficult for young children to disassemble. The owner places the slide assembly 14 and the main electronic probe assembly 12 on either side of the firearm 20 and pushes them together to ensure a snug fit, being careful to make sure that the blocking cam 17 stem enters the narrow receiving socket 73 located on the slide assembly 14.

Disassembling the trigger block 22 is straight forward. It is prudent to practice quick disassembly of the trigger block 22 before programming it for use out of the sight of children. The owner grasps the slide assembly's elastomer cover 80 between the thumb and index finger and pressing in on both sides, disengages the slide assembly 14 from the main enclosure assembly 12. The opposite hand holds the main enclosure assembly 12 to ensure that it does not fall from the firearm 20. Gently pulling apart the main enclosure assembly 12 and the slide assembly 14 from each other results in disassembly of the trigger block 22 from the firearm 20.

The installed trigger block 22 is easily programmed according to accompanying printed directions and a video. First the firearm 20 is in the position to be stored, for example with the slide assembly 14 down and the keypad 87 up.

EXAMPLE 1

A new embodiment of the trigger block 22 has been invented with additional unique features. First, there is a keypad 87 with numbers 1-4 for a typical entry of the owner's personal code. There are expanded functions available with the use of the two other indicators which provide a quicker unlocking of the inventive trigger block 10, which is particularly helpful in a defensive situation. The depressible release ends 68 have been strengthened with stronger biasing elements 72 to accommodate more force to deter separating the two sides of the latch without the proper control. Furthermore, the parallel teeth 33 on the tapered probe element 16 have been enlarged (lengthened laterally, with significantly more volume and mass in each) to provide more tooth strength for better retention. Moreover, we have designed additional options for the blocking cam 17. Let us now focus on the new device changes.

FIG. 13 shows another embodiment of a trigger block 10. This trigger block 10 also includes a main enclosure assembly 12 and a slide assembly 14. The main enclosure assembly 12 has a keypad 87 with keys marked 1, 2, 3, 4 and a command key (concentric circles) 89 and a check key 91 for confirmation. There are also two indicator lights 83 red and blue. Their purposes are discussed with the installation and operation directions. FIG. 13 also shows the tapered probe element 16 with fewer and larger parallel teeth 33. The larger parallel teeth 33 each have more mass and strength to make the trigger block 22 even harder to remove. Deeper parallel teeth 33 also make it even more difficult for one to loosen the trigger block 10 by twisting the two parts of the device.

FIG. 14 shows the two vent screens 93 that cover two alarms 53. The two alarms 53 can sound simultaneously or differently for different perturbations. In yet another embodiment, we satisfy the complaint of some testers that the 85 dB alarm in the earlier embodiment was not loud enough. Two ways have been tested. First, an additional alarm speaker was added next to the first speaker, as well as an additional vent for sound transmission. From the two speakers, this embodiment provides over 120 dB of noise. Preferably the noise range is about 50 to about 200 dB, more preferably about 60 to 150 dB and most preferably 75 to 130 dB. An alternative has a separate activator trigger for the second alarm, which is generated by the magnetic reed switch 52 found in the tapered probe element 16; separation of the tapered probe element 16 from its central channel 63 in the slide assembly 14. Such a separate alarm is optionally activated by separation of other parts of the trigger block 10.

Another embodiment for improved alerting of parents and others involves a BLUETOOTH transducer/speaker/personal carry Super Alarm (not shown). This internal device provides BLUETOOTH coupling capability with the ability to have a separate alarm ring in another part of the building in which the device is used (e.g., home or office) or carried on the authorized user's person. This expanded capability allows users to know if the engaged firearm 20 has been moved or manipulated—whether the owner is anywhere in a home, garage, outside patio or yard.

This new embodiment has been designed to fit into the main enclosure assembly housing 15 that can be any convenient size. In one embodiment of the main enclosure assembly 12, the available space is about 45 mm by 80 mm by 25 mm. FIG. 15 shows the battery power source 56, with a USB outlet 95 to the left for recharging the battery. In addition to the USB outlet 95, the alarm device has three switches (not shown) to interact with the different parts of the device. A power on/off switch is a movable lever that can turn the device on and off and is designed to be touch safe, in that the user has to switch it to make it work: A simple touch will not turn this switch on or off. An optional nano-lock switch is a button-like switch. It is similar to the power switch, where the user cannot easily turn it on or off. The user can turn on the nano-lock switch when the super alarm sounds. The nano-lock switch prevents the slide assembly 14 from being removed. Once the slide assembly 14 is locked, it cannot be quick-removed with the two buttons, only entering the passcode into the keypad 87 releases the nano-lock. And finally the couple button is used to couple this alarm with one or multiple trigger blocks 10. The user performs the coupling by pressing three keypad 87 buttons (command, 4 and check) and the couple button. This alarm can be coupled to more trigger blocks 10, and one trigger block 22 can be coupled to multiple alarms, which makes even more noise, so long as the devices' BLUETOOTH function is within an effective range (about 30 feet radius).

FIG. 16 shows another embodiment of outer end 62 on the slide block 14 to accommodate the different profile of the tapered probe element 16 with a different configuration of the parallel teeth 33 (see below). The tapered probe element 16 inserts into the slide block 14 when the latch end 67 is held open. The tapered probe element 16 fits snugly into a central channel 63, making it more difficult for anyone to twist the slide assembly 14 loose from the main enclosure assembly 12.

FIG. 17 shows a cutaway view of both the main enclosure assembly 12 and the slide assembly 14. It is easier to see the tapered probe element 16 which slides into the central channel 63 of the slide assembly 14. This new tapered probe element 16 has a different profile with larger parallel teeth 33 on only the middle portion of the longitudinal side of the tapered probe element 16. The parallel teeth 33 are positioned to enter the central channel 63 and be caught by the latch end 67 in the slide assembly 14. The new parallel teeth 33 are preferably not symmetrical as they emerge from the side of the tapered probe element 16, the better to catch in the latch ends 67. Note that flange 44 also has a shorter profile from FIG. 4.

FIGS. 18A-C show three different flange 44 profiles with the same design for the cam central post 40. Our extensive testing with a large variety of firearms indicates a need for different designs to accommodate different spaces behind the firearm's trigger 23. We found that FIG. 18A accommodated about 75% of tested firearms. Most of the other firearms were accommodated by flange 44B (FIG. 18B). We designed FIG. 18C to accommodate other firearms, particularly those with lateral holes (not shown) in the trigger 23.

FIG. 19 is an exploded version of another embodiment of FIG. 5. Here the cover 58 at the upper left has two vent screens 93 and screws 45 for attachment. Next are the two signaling elements 53 and a camera 55 facing the front of the keypad 87. The control unit 85 is shown with one large power source 56 and two smaller ones above. The batteries as shown can be connected in series or attached to different functional components. There can be single or multiple replaceable batteries or conveniently one rechargeable battery (see below) for exemplary connection thereof.

FIG. 20 is an exploded version displaying details of another embodiment of the slide block 14. The pawl elements 65 or latch have been removed for better illustration. The elastomer cover 80 has also been removed. The biasing elements 72 are chosen for their resistance to owner pressure and child difficulty.

FIG. 21 is a cutaway view of the improved latch or pawl elements 65. The parallel teeth 33 have been improved to accept the latch ends 67 more deeply for stronger engagement and difficulty of removal without appropriate operation. Note the arrows D showing that depressing the pawl elements 65, particularly the release end 68 opens the latch. Also shown is the working relationship of spring biasing elements 72 that in use maintain pressure to keep the latch ends 67 in place and the trigger block 10 secured.

FIGS. 22A and 22B are schematics that show a cross sectional profile of the main enclosure assembly 12 with an example of three of the many possible locations of internal cameras 55 (FIG. 22A) and a top view showing camera 55 placement near the keypad 87. The cameras 55 are so arranged to capture an image of an individual tapping the keys in an effort to separate the trigger block 22 from the firearm 20. FIG. 22A shows a preferred camera 55 placement with one camera lined up with the keypad 87 and the other two cameras 55 on either side at an angle to collectively cover a wide area. Nearby are a battery power source 56 to operate the cameras 55 and PCB's to control and receive information from the cameras 55. There is also shown a preferred location for the optional fingerprint reader 97. FIG. 22B also shows an optional SIM card 99 for strong unique identifiers, which is particularly helpful for integration of the trigger block 10 with smart phones and security systems.

To make it more convenient for trigger block 10 to provide more electronic services, another embodiment is a larger rechargeable battery (not shown).Yet another embodiment supports additional electronic features (see above) of the trigger block 22. In this new design, the tapered probe is redesigned at its distal end 32 to accommodate a USB port 95 with an electrical connection to rechargeable batteries (not shown) in the interior volume 28 of housing 15 (see FIG. 4). This provides a convenient way to charge and recharge the batteries (including but not limited to lithium batteries) that support the motion sensor 71, alarms, transmitters, receiver (operating locking mechanisms), cameras, and the like.

EXAMPLE 2

We have invented a new hidden lock system, a nano-lock 101 to be used in addition to the trigger block 10 with quick-release latch disclosed above. We call it the nano-lock because it is even smaller and is operated with a nano-motor that uses very little electricity. The locking system can be activated or deactivated by keypad 87 or by fingerprint reader 97. Optionally the nano-lock can be activated by remote activation (e.g., BLUETOOTH) or by an alarm. The authorized user can optionally program an activation time delay. In one embodiment, the user inputs the delay in seconds; in another embodiment, the user selects time delays, including but not limited to 0, 3, 5, 7 or 10 seconds. Once activated, the lock can only be released (and the device disassembled) by entering the correct password or by recognition of a fingerprint scan.

In the current embodiment, the nano-lock 101 resides inside the tapered probe element 16 of the main enclosure assembly 12, as shown in FIG. 23. The parts of nano lock 101 are assembled within the tapered probe element 16. At the right of FIG. 23 is nanomotor 103 with gears which connect to control bar 105. The other end of the control bar 105 connects to a moving bar 109. When the nanomotor 103 pushes the control bar 105 away from the nanomotor 103, the moving bar 109 pushes laterally on the nano-lock hook arm 107 which moves laterally from the lock pivot pin 111. This causes the distal hook of the nano-lock hook arm 107 to enter the space between the locking steps 113 that are situated in the central channel 63 of the slide assembly 14. This is the locked position; the nano-lock hook arms 107 are designed to tighten in the locking steps 113 as a person tries to pull the two sides of the trigger lock 10 apart. To keep the nano-lock 101 centered in the locking steps 113 on opposite sides of the nano-lock 101, the nano-lock 101 is optionally provided with a glide bar 115 on which the moving bar 109 moves left to disengage from the locking steps 113 and to the right to push the nano-lock hook arms 107 away from the locking steps 113.

EXAMPLE 3

Another embodiment of the inventive trigger block 10 pairs the trigger block with a remote control 105. The remote control 105 is provided with detailed instructions (not shown) for set up and operation of numerous functions, including controlling up to 30 trigger blocks 10 and a stealth camera (see below). An example of a remote control device is shown in FIG. 24. This remote control 105 has a main enclosure 110 of hard plastic or other strong material. At one end is a battery holder 115 that takes regular disposable batteries or can hold rechargeable batteries, for which that end also has a USB port for recharging. On the cover are a keypad and an OLED screen 120 and the remote keypad 125. The remote control 105 is turned on by pressing a power key in the remote keypad 125. A password is required that when input unlocks the main menu OLED screen 120; after four failed attempts, the remote control 105 locks up. That screen displays the battery power remaining in the remote control device 105.

The remote control 105 needs to be coupled to the trigger block 10, a process performed from either the remote control 105 or the trigger block 10, so long as the two devices are within two meters of each other. If the two devices are not within range a voice message reports “no Remote Control device detected.” The same process is repeated for each trigger block 10 coupling to the remote control 105.

The remote control 105 is provided with two menus, the main menu with commonly used commands and the option menu with set up commands. The main menu enables arming, disarming, password entry, sound control, battery and coupling. The option menu provides the additional functions of sensors, sound set up, voice message and sensitivity. Arm activates all trigger blocks 10 coupled with the remote control 105. For each numbered trigger block 10, the OLED screen 120 even displays the electronic battery and alarm battery status along with the armed confirmation. When the user disarms by remote control 105, the OLED screen 120 again displays all coupled devices and battery status. The Password command presents a screen to confirm or reject the input password, as well as the ability to change the password. The Sounds menu enables the user to change and interchange the alarm sounds of the trigger block 10 devices with three options: 1) play the alarm sound for the motion sensor alarm on each trigger block 10, b) play the alarm for removal of the trigger block, and c) swap the alarm sound between the motion sensor alarm and the trigger block removal alarm. The Battery menu enables the user to check the battery status of not only the remote control 105, but also any coupled trigger block 10 and the remote camera 130. The Couple menu enables adding a trigger block 10 or remote camera 130 and checking the lists of trigger blocks 10 and of remote cameras 130 and their battery status.

On the Option menu, the sensor options allow the user to change the alarm sensor options of all the coupled trigger blocks 10, with the options being a) motion and trigger block for engaging both the trigger block removal alarm and motion sensor alarm, b) the motion alarm only for engaging only the motion sensor, and c) trigger block alarm only for engaging only the trigger block removal alarm. When one alarm alone is chosen, the other alarm is disabled. The Sound options enable the user to select the sounds or tones of the alarms and keypad function (clicking sound) on any coupled trigger blocks 10. Upon selecting keypad, the keypad 87 on the trigger blocks 10 makes a sound when pressing the keys or not. Upon selecting Motion, the user selects any of four sounds. Upon selecting trigger block 10, the user selects any of four sounds. The Voice Message options enable the user to select English, Spanish or no voice message. Of course, different languages can be programmed as required. And finally the Sensitivity options permit selection of high, medium or low sensitivity of the motion sensor alarm of all of the coupled trigger blocks 10.

A small remote camera 130 enables the capture of still and video images when the alarm of the trigger block 10 is activated. Like the trigger block 10, the remote camera 130 is coupled to the remote control 105 via BLUETOOTH technology. Stealth or spy cameras are available in many different configurations, including hidden within clock radios, dolls or merely attached to the underside of a shelf. The small remote camera 130 is positioned away from the trigger-blocked firearms so as to obtain a view of the disturber's face, etc. Regardless of the shape of the camera, it has the features shown in FIG. 25. FIG. 25A shows the front of an exemplary remote camera 130, with the camera main enclosure 135 and infrared lights 140. FIG. 25B shows a side view of the remote camera 130 with a micro SD slot and card 145 and a coupling button 150. FIG. 25C shows the bottom of the remote camera 130 with a USB outlet 155 that can recharge an internal battery (not shown) and download the still and video images. The micro SD card is capable of storing at least one hour of video. The remote camera 130 can be coupled to the remote control 105 using either device. The remote control 105 enables all the trigger blocks 10 to be linked to the remote camera 130; whenever either alarm on any device is activated, the remote camera 130 starts to take still pictures and record video images simultaneously for about 15 minutes. The time duration can be set from 1 minute to the life of the camera battery (about one hour) or any duration in between. Preferably the remote camera 130 is set up within about 20 feet from a coupled trigger block 10. The remote camera 130 is preferably set up in a place or on an object hidden from the view of unauthorized users.
